Un milione di zanzare è stato liberato nell'ambiente a Fresno, in California. Niente paura però, si tratta di un esperimento volto a diminuire la popolazione di questi insetti. In che modo? Vi chiederete….
Il progetto "Debug Fresno", nato dal cosiddetto braccio scientifico di Google, prevede che questi animali infettati dal batterio wolbachia, non pericoloso per l’uomo, rendano impossibile la schiusa di uova qualora una “femmina” autoctona si accoppi con uno di questi maschi malati.
I ricercatori prevedono di rilasciarne un milione alla settimana per cinque mesi. La specie colpita è la Aedes Aegypti, presente nella zona dal 2013 e che in altre parti del mondo è responsabile della trasmissione di zika, dengue, Chikungunya e febbre gialla.
